automatic monitoring system Applications

The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

Digital Pathology is an image-based information environment enabled by virtual microscopy. This involves imaging glass slides and saving and distributing their digital images for analysis, archiving and storage.
The virtual microscopy slides are:
•Scanned — using a microscope based scanning device that takes images of the whole slide via large scanning or stitching of smaller scans. This involves a motorized stage to scan the whole slide. Light source stability is important for scanning in order to prevent illumination variation across the whole scan. The X-Cite® exacte is commonly used in slide scanning systems.
•Viewed — on a computer via viewing software
•Managed — some of the slides have a barcode that is also scanned to enable archiving with patient information
•Analysed — using image analysis tools and software, structures maybe automatically identified and quantified
•Shared — digital pathology files may be shared over a network to gather additional expert opinion
Digital pathology technology in no way replaces the expert eye and diagnosing power of a pathologist and a doctor. The only thing it saves is time to image the samples and also provides an efficient and organized way to archive the virtual microscopy slides for future consultations, record-keeping and disease comparison.

Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment. Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations. Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.

Protea can supply fixed workplace monitoring systems that can measure single or multi-points about the workplace. Specifically designed analytical systems can ensure detection limits down to ppb levels can be achieved for multiple gases with a single instrument. Controlling software can run automatically, providing instantaneous or time-weighted average readings.

The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these organisms at the entrance and exit of the canal, generating alarms in the presence of toxic substances.

To abide local regulations, and ensure efficient and effective composting, the temperatures of the windrows must be measured and logged constantly. With accurate temperature measurements, you can determine the optimum time to turn the windrows for quicker compost production.
Time consuming and error prone manual data collection is eliminated using a SureCross FlexPower Node equipped with three thermocouples to automatically monitor the temperature at three depths within a compost windrow. Temperature sensor readings are wirelessly transmitted back to the Gateway or host system for data collection, analysis, and logging.
Because the temperatures are measured and recorded continuously, the composting rows can be turned as soon as the temperature reaches the ideal point.
Continuously monitoring the temperature will also provide an early warning to potential fire hazards by notifying personnel when temperatures exceed recommended ranges, thereby preserving the product.

SedEvent is an event-driven, automatic grab sampling system that provides a simple and practical method of accurately determining suspended sediment and nutrient loads.
While suspended sediment concentration (SSC) cannot be directly measured accurately or reliably, turbidity has been shown to be an excellent surrogate for SSC. Turbidity is caused by suspended particulate matter such as clay, silt, algae, organic and inorganic chemicals and acids like fertilizers, and microscopic organisms like harmful bacteria. These contents give water its cloudy or turbid appearance, and turbidity in natural waters is recognized as an important indicator of natural health.
Measuring suspended sediment concentrations used to be labor-intensive, costly, inaccurate and impractical. SedEvent not only makes it possible and practical, it makes it simple.

In a pit water purification system it was necessary to detect the discharge volumes. The operator wanted a regular and automatic transmission of readings. On the selected measurement place no mains power connection was available. Due to the risk of vandalism, it was not planned to install a switching cabinet.
See the NIVUS solution for this measurement task here.

The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.

The safe extraction of valuable raw materials: robots automatically dismantle monitors containing mercury, while protecting workers’ health at the same time.
According to initial projections, around three million LCD screens will be recycled in Germany in 2016. However, their backlighting system often contains mercury, which means they are classified as 'hazardous waste' in accordance with the EWC, and as 'Collection Group 3' in accordance with the Electrical and Electronic Appliance Law. They also contain valuable raw materials, such as metals and plastics, which have to be recovered in such a way, that the environment is not harmed. However, recycling specialists, Erdwich Zerkleinerungssysteme GmbH, have now developed an alternative: The company from Kaufering has developed an automatic processing system that enables mercury and other valuable raw materials to be easily extracted and recycled in an environmentally-friendly way.
